"Through the door."
"You pushed the bolt and fastened the chain!"
"A good deal later! By that time, she must have left the house."
"And the crime was committed, you think, after she went?"
"Of course."
They searched the house from top to bottom, from the garrets to the cellars; but the murderer had fled. How? When? Was it he or an accomplice who had thought proper to return to the scene of the crime and do away with anything that might have betrayed him? Those were the questions that suggested themselves to the police.
The divisional surgeon came upon the scene at seven o'clock, the head of the detective-service at eight. Next came the turn of the public prosecutor and the examining magistrate. In addition, the house was filled with policemen, inspectors, journalists, Baron d'Hautrec's nephew and other members of the family.
They rummaged about, they studied the position of the body, according to Charles's recollection, they questioned Sœur Auguste the moment she arrived. They discovered nothing. At most, Sœur Auguste was surprised at the disappearance of Antoinette Bréhat. She had engaged the girl twelve days before, on the strength of excellent references, and refused to believe that she could have abandoned the sick man confided to her care, to go running about at night alone.
